Abstract

A packet-switching network may contain links with variable bandwidths
(e.g., copper and radio). The bandwidth of such links is sensitive
to the external environment (e.g., climate). Availability is
typically used to describe these links when doing network planning.
This document introduces an optional Bandwidth Availability TLV in
RSVP-TE signaling. This extension can be used to set up a GMPLS
Label Switched Path (LSP) in conjunction with the Ethernet
SENDER_TSPEC object.
